Debra Stephenson and Jon Culshaw take over 'This Morning'

A surprise was in store for *This Morning* hosts Eamonn Holmes and Ruth Langsford earlier today when guests Jon Culshaw and Debra Stephenson - stars of BBC Radio 4 'Dead Ringers' - opened the show in identical outfits, portraying the married couple to viewers.

During the sketch, Eamonn and Ruth were seen laughing at the side of the studio, before Ruth admitted, "That is the weirdest experience! But very good, thank you very much."

Eamonn joked, "If only my wife looked like you... I can only dream!"

Later during their interview [and dressed as themselves] Debra admitted she will miss not getting fully made up for character sketches on radio. She said, "I quite like the dressing up actually... and it gives you a lot of time to get into character."

Jon revealed how some characters are quicker to do than others, he said, "Someone like Simon Cowell is quite quick - he doesn't move a lot and [makes] choppy sort of gesticulations like that."

Ruth said, "Eamonn said he felt unnerved because he knows you're watching him and his mannerisms..."

Jon replied, "[Slipping into his Eamonn impression] It's great to see Eamonn in sofa mode, very relaxed."

Ruth added, "I see you do the knee rub, and he [Eamonn] doesn't even know he's doing it!"

Jon said, "Certain characters do put you in a good mood and you feel relaxed, and that happens when I put on your voice so it does - Ozzy Osbourne puts you in a good mood as well!"
